ABSTRACT

A pigmented anhydrous cosmetic composition for reducing the shiny appearance of skin and cosmetically improving the appearance of skin imperfections comprising a cosmetically effective amount of mushroom extract and a method for reducing the shiny appearance of skin and cosmetically improving the appearance of skin imperfections comprising applying to the skin an anhydrous cosmetic composition containing mushroom extract.

TECHNICAL FIELD

The invention is in the field of cosmetic composition for application toskin.

BACKGROUND OF THE INVENTION

Oil and sebaceous secretions protect facial skin against moisture lossby forming a superficial film on the skin surface that locks in skinmoisture. In general, reduced oil secretion causes dry skin andexcessive oil secretion causes oily skin. Ideally the skin should bebalanced, which means that the skin should secrete exactly the correctamount of oil to keep the skin hydrated and smooth, but not enough oilto give the undesirable shiny appearance or promote blemish formation.Since facial skin is rarely perfect, cosmetic manufacturers mustformulate their products to ameliorate less than perfect skin types.

One particularly undesirable feature of oily skin is the resulting shinethat quickly appears on the skin surface as oil is secreted by the skin.Shiny skin looks greasy. It also tends to show more imperfections thanskin that exhibits a matte surface. One standard method of treatingshiny, oily skin is to apply cosmetics that contain various types ofparticulate absorbent agents. One example of such a product is“Cornsilk” a commercial loose powder. When the powder is applied to oilyskin the various types of particulates absorb excess skin oil and mattethe skin. One problem with Cornsilk and other products containingoil-absorbing particulates is that the particulates cake or streak inaddition to providing a mask-like effect when the application is tooheavy. In addition, layers of oil-laden particulates on the skin canclog skin pores and promote blemish formation.

Another approach to counteracting oily skin is found in the so-called“oil-free” cosmetic formula. The idea behind these products is not toaggravate the oily condition by adding oils to the cosmetic the userwill apply to skin that already secretes too much oil. Low viscositysilicone oils, which tend to flash off fairly soon after the cosmetic isapplied to the skin, are typically used in these formulas. One problemwith “oil-free” formulas is that they do nothing to ameliorate theeffects of excessive oil. Nor do such formulas do anything to minimizethe undesirable shiny appearance of oily skin.

Clearly there is a need for anhydrous products that are capable ofreducing the undesirable shiny appearance of skin having excessive oilon its surface, without overly matting the skin with absorbents thatgive a cakey, made-up look.

Most unexpectedly, it has been discovered that anhydrous cosmeticsformulated with mushroom extract are excellent for use on all skin typesincluding oily skins. Such cosmetics are able to reduce the shinyappearance of skin and thereby aid in cosmetically improving theappearance of skin imperfections such as blemishes, wrinkles, and finelines. At the same time these formulas do not provide the heavy made-uplook that is often seen in compositions containing oil-blottingabsorbent powders.

It is an object of the invention to provide an anhydrous cosmeticcomposition for reducing the shiny appearance of skin having excess oilon its surface.

It is further object of the invention to provide an anhydrous cosmeticformula for cosmetically improving the appearance of skin imperfectionssuch as fine lines, wrinkles, and blemishes.

It is a further object of the invention to provide a pigmented anhydrouspowder-type makeup for ameliorating the adverse effects of oily skin.

Generally, a cosmeticallyeffective amount ranges from about 0.01-10%, preferably about 0.05-8%,more preferably about 0.1-7%. These percentages refer to the mushroomcontent only, not any other extraneous solids in which it is dispersed.For example, it may be desired to disperse the mushroom powder with oneor more additional pigments or powders. The mushroom powder ispreferably extracted from the pulp of a mushroom of the genus Fomes orPolyporus, e.g. Fomes officinalis or Polyporus officinalis. Particularlypreferred is a mushroom powder sold by Active Concepts, SouthPlainfield, N.J., under the product name ABS Mushroom Extract—powder.

Preferably thetotal oil content is in the range of about 0.1-75%, preferably 1-70%,more preferably 5-65% by weight of the total composition. The term“volatile” means that the oil has a vapor pressure of at least 2 mm. ofmercury at 20° C. The term “non-volatile” means that the oil has a vaporpressure of less than 2 mm. of mercury at 20° C. Either silicone ororganic oils are suitable provided that the oils are compatible, i.e.soluble in each other.

1. Volatile Oils

Suitable volatile oils include cyclic silicones having the generalformula:

where n=3-6.

Also suitable are linear volatile silicones in accordance with theinvention have the general formula:

(CH₃)₃Si—O—[Si(CH₃)₂—O]_(n)—Si(CH₃)₃

where n=0-6.

Linear and cyclic volatile silicones are available from variouscommercial sources including Dow Corning Corporation and GeneralElectric. The Dow Corning volatile silicones are sold under thetradenames Dow Corning 244, 245, 344, and 200 fluids. These fluidscomprise octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane,hexamethyldisiloxane, and mixtures thereof.

Also suitable as the volatile oils are various straight or branchedchain paraffinic hydrocarbons having about 5 to 40 carbon atoms, morepreferably about 8-20 carbon atoms. Suitable hydrocarbons includepentane, hexane, heptane, decane, dodecane, tetradecane, tridecane, andC₈₋₂₀ isoparaffins as disclosed in U.S. Pat. Nos. 3,439,088 and3,818,105, both of which are hereby incorporated by reference. Preferredvolatile paraffinic hydrocarbons have a molecular weight of about70-225, preferably about 160 to 190 and a boiling point range of about30 to 320, preferably 60-260 degrees C., and a viscosity of less thanabout 10 es. at 25 degrees C. Such paraffinic hydrocarbons are availablefrom EXXON under the ISOPARS trademark, and from the PermethylCorporation. Suitable C₁₂ isoparaffins are manufactured by PermethylCorporation under the tradename Permethyl 99A. Another C₁₂ isoparaffin(isododecane) is distributed by Presperse under the tradename Permethyl99A. Various C₁₆ isoparaffins commercially available, such asisohexadecane (having the tradename Permethyl R), are also suitable.

The presence of the volatile silicone enables the makeup todry on the skin in an appropriate period of time, and minimizes theheavy, greasy feel that is occasionally found with nonvolatile oils. Theremaining nonvolatile oil phase acts to plasticize the film formed onthe skin by the dried cosmetic composition.
